 # Make Invidious requests data from YouTube through a VPN using Gluetun (in case your IP is blocked)
 
+??? warning "No guarantees"
+
+    This tutorial does not guarantee Invidious to function again. This depends on the public IP address from the VPN that you will be using.
+    
+    YouTube has blocked datacenter IP addresses. If you are using the IP address of a well known VPN provider, this won't solve your issues.
+
+    IP addresses that may not be blocked are residential IP addresses (like at home).
+
+    If following this tutorial made Invidious working again, there is no guarantee that it will keep functioning forever. YouTube may detect traffic coming from Invidious and block your public IP address.
